The invention relates to a crane comprising a movable undercarriage, a superstructure mounted rotatably on the undercarriage, a boom connected to the superstructure in a luffable manner, a derrick boom connected to the superstructure in an articulated manner, via which the boom is braced, a crane control system, a guide connected to the superstructure, and a derrick ballast. The derrick ballast comprises a ballast plate for stacking ballast elements, which is connected to the derrick boom via the ballast bracing and to the superstructure via the guide, as well as a ballast wagon. The ballast wagon comprises a standard heavy-load transport device with its own drive and drive control. According to the invention, the guide is connected to the ballast plate or the ballast wagon via a connection device which comprises a measuring device and is configured to detect a force which counteracts a relative movement between the ballast wagon and the guide. According to the invention, the crane control is connected to the drive control of the heavy-load transport device via a control connection and is configured to control and/or regulate the heavy-load transport device depending on the force detected by the measuring device.
